Is there any way to offset curve and filling space between with mesh to make a ring?
I would recommend using the Taurus mesh to start with. You then can select the top and bottom ring of the Taurus to make it look like this.
I Created more rings using cntl+r so I could use smaller sections. 
This isn't to complicated but the tutorials by: Blender Guru might help as they go over the basics and he makes a lot of objects. If you need tutorials that is.

Edit: I forgot to say then you can extrude from a plane and make it connect off of multiple extrudes.
